Proximal avulsion fractures of the 5th metatarsal (pseudo-Jones)


This fracture is an avulsion of the base of the 5th metatarsal, which often does not extend into the metatarsocuboid joint.

It involves the peroneus brevis pulling on the tip of the 5th metatarsal.


Clinical signs

The clinical picture includes swelling, ecchymosis, and pain over the base of the 5th metatarsal.


Conventional radiographs of the foot (AP, lateral, and oblique views) are sufficient for diagnosis and treatment.
